Biography
Dr. Silcox is a vertebrate paleontologist, specializing on fossil mammals. She is particularly interested in using the fossil record to understand the earliest phases of primate evolution. Much of her work centres on the “Plesiadapiformes”, the first adaptive radiation of primates. Appearing some 65 million years ago, plesiadapiforms diversified into over 140 known species, with a broad range of dietary and locomotor specializations. Dr. Silcox regularly does fieldwork in the Western United States (Wyoming, Montana) to enrich the fossil record for this and other Paleocene and Eocene mammalian groups. Particular areas of recent focus include the evolution of the brain in early primates, and clarifying the evolutionary position of Primates in the broader phylogenetic context of Mammalia.
